Introduction: Why Spiders Matter in South Carolina
If you live in South Carolina, you’ve had a spider encounter. Maybe it was a wolf spider bolting across your Columbia garage, an orb weaver web stretched across your Lexington mailbox, or a suspicious shiny black spider under your Lake Murray deck chair.
Spiders are simply part of life here. The Midlands’ warm, humid climate provides a year-round buffet of insects, and where there are bugs—there will be spiders.
Most are harmless, some are even beneficial (think natural mosquito control), but a few—like the Black Widow—deserve serious caution. And even the harmless ones can be unsettling when they’re hanging in your doorway or surprising you in the shower.
At Lamp’s Pest Solutions, we’ve been helping Midlands homeowners since 2009 deal with every type of spider encounter—from harmless house spiders to invasive Jorō spiders stretching webs across driveways. This guide is your complete breakdown of South Carolina’s spiders: how to identify them, myths you should ignore, prevention tips, and when to call in the pros.

Spiders in South Carolina at a Glance
Diversity: Hundreds of species thrive in SC’s warm, humid climate.
Role: Most are beneficial, eating flies, mosquitoes, gnats, and even roaches.

Invasive species: Jorō spiders are spreading rapidly; Brown Widows are expanding their range.
Seasonality: Activity peaks in late summer and fall, but indoors they’re found year-round.
Common Native Spiders of South Carolina
Wolf Spiders
Big, hairy, and fast—wolf spiders are among the most intimidating spiders homeowners encounter. But their bark is far worse than their bite.
Appearance: Brown or gray, up to 1.5 inches, hairy.
Where they show up: Garages, basements, laundry rooms, and under leaves.
Behavior: Hunt instead of spinning webs. Females carry egg sacs on their backs.
Danger: Not venomous to humans, but may bite if handled.
📍 Lexington Story: A Lake Murray homeowner once called us after “a tarantula” ran across their laundry room. It was just a wolf spider. Harmless, but terrifying. We sealed gaps under the back door and applied treatment—problem solved.
Jumping Spiders
Tiny but bold, these spiders are often noticed because they stare right back at you with their big eyes.
Appearance: Small, compact, black with white or colored spots.
Where they show up: Sunrooms, windowsills, porches, and gardens.
Behavior: Stalk prey and leap several times their body length.
Danger: Harmless.
📍 Columbia Note: A customer described “tiny black spiders staring at me in the sunroom.” They were jumping spiders hunting flies. Creepy? Yes. Harmful? Not at all.
Orb Weavers (Banana Spiders)
These are the iconic web-builders of the South Carolina summer.
Appearance: Varies, but golden silk orb weavers (“banana spiders”) are large and yellow.
Where they show up: Gardens, porches, mailboxes, between trees.
Behavior: Spin massive, wheel-shaped webs at night; rebuild daily.
Danger: Harmless, but their webs can be obstacle courses.
📍 Irmo Story: A family had to duck under a huge orb weaver web on their way to the mailbox every morning. We cleared the webs and advised reducing porch lights to discourage flying insects (orb weavers’ food).
Southern House Spiders
Often mistaken for Brown Recluses, these spiders are dusty-looking but harmless.
Appearance: Brown, long-legged, dusty.
Where they show up: Attics, barns, sheds, and window frames.
Danger: Harmless.
📍 Gilbert Story: A family thought their attic was full of recluses. They were Southern House Spiders. We cleared webs, treated, and gave them peace of mind.
Cellar Spiders (Daddy Longlegs)
These delicate spiders are frequent basement dwellers.
Appearance: Tiny bodies, long legs, pale gray.
Where they show up: Crawlspaces, basements, garages.
Behavior: Spin messy webs; shake violently when disturbed.
Myth: They’re “the most venomous spiders but can’t bite humans.” False. Harmless.
📍 Red Bank Note: We often find them in garage corners. Customers don’t like the look, but they’re not dangerous.
Crab Spiders
Masters of camouflage, crab spiders blend into flowers and shrubs.
Appearance: Crab-like shape, often brightly colored or flower-matching.
Where they show up: Shrubs, flowers, gardens.
Behavior: Ambush predators, no large webs.
Danger: Harmless.
Venomous or Risky Spiders in South Carolina
Black Widow Spiders
South Carolina’s most infamous spider.
Appearance: Glossy black with a red hourglass marking.
Where they show up: Woodpiles, crawlspaces, sheds, lawn furniture.
Danger: Bites cause severe pain, muscle cramps, sweating.
Behavior: Shy but defensive if disturbed.
📍 Columbia Story: A homeowner spotted one under a patio chair. We removed it, treated the yard, and advised safe firewood storage.
👉 Don’t DIY Black Widow removal. Call 803-414-0588.
Brown Widow Spiders
Cousins of the Black Widow, but rapidly spreading.
Appearance: Tan/brown, orange hourglass, spiky egg sacs.
Where they show up: Patio furniture, fences, sheds, mailboxes.
Danger: Less venomous than Black Widows, but still painful.
Behavior: Thrive around human structures.
📍 Red Bank Story: Dozens of spiky egg sacs under patio chairs. Confirmed Brown Widows—we cleared the infestation.
Brown Recluse Spiders
Rare in South Carolina, but feared.
Appearance: Light brown with violin-shaped marking.
Where they show up: Closets, attics, storage boxes.
Danger: Bites can cause necrosis, though verified SC cases are rare.
📍 Lexington Story: A family thought they had recluses in their basement. They were Southern House Spiders. We reassured them and treated.
Invasive & Emerging Spiders in South Carolina
The Jorō Spider
The Midlands’ most talked-about new arrival.
Appearance: Bright yellow with blue stripes, long legs, massive golden webs.
Where they show up: Porches, driveways, power lines.
Danger: Harmless, despite their size.
Impact: Huge webs disrupt outdoor living.
📍 Lexington Story: A resident couldn’t pull into their driveway because of a Jorō web. We removed it, treated the yard, and advised reducing outdoor lights.

Summer: Populations surge; webs everywhere.
Fall: Cooler nights push spiders indoors—peak season.
